[N6O2-8].Actun TohCranial:Temporal bone, nearly complete (figure 6.3). Human.The individual may have been immature, as thesutures had not yet joined (although in some rare individualsit does not join). This individual is robust ascompared to other members of the local population(which generally indicates a male, particularly in lightof its immature status). There is some porosity of thebone surrounding the external auditory meatus. Thisis evidence of porotic hyperostosis, which is the bonylandmark of anemia (White 1991:346), common inimmature individuals. [Lot SJ205-13].Postcranial:Long bone midshaft fragment.
